The plant prefers regular water during its growth cycle but does not require watering during the winter months. However, it should be kept evenly moist throughout its life cycle so that roots will develop properly without damage from drought conditions.
You can use both cuttings and seeds to propagate frangipani. As the plants contain a poisonous sap, ensure you wear gloves when handling the cuttings and pruning. Pollination is essential to Plumeria so that fruit with seeds can form.
As frangipani hails originally from tropical regions, its best performance will be in the tropics and sub-tropics.
Keep temperatures indoors 26 to 32°C. If that temperature is too high for indoor living, the Plumeria will do just fine with daytime temperatures of 23°C and night temperatures of 15 to 21°C.
Frangipani rust, also known as Coleosporium pluymeriae, is a fungal plant disease that affects frangipani trees in Australia. It is spread by spores being picked up by the wind and implanted on damp leaves. There is no cure and no sprays are registered against it. To manage the spread of the disease, it is important to remove infected leaves as soon as possible and not to shake them as you do so. No products are registered specifically against it, but myclobutanil and copper are registered for rust in ornamentals.
